Transmission losses

Definition

Transmission losses refer to the loss of energy that occurs when electrical energy is transferred from one point to another, particularly in photovoltaic devices. These losses can arise from a variety of factors, including resistive heating in conductors, reflection at interfaces, and absorption within materials. Understanding these losses is crucial for improving the efficiency and performance of photovoltaic systems.
